The radiocarbon dating lab is based in Miami, Florida, and is the world leader in Carbon-14 analyses since 1979.
It has forwarding offices in Australia, Brazil, China, Japan, South Korea, Taiwan, and the UK.
For example, the image on the right is a simulation of many identical atoms undergoing radioactive decay.
Note that after one half-life there are not exactly one-half of the atoms remaining, only approximately, because of the random variation in the process.
However, unlike in an exponential decay, the half-life depends on the initial quantity, and the prospective half-life will change over time as the quantity decays.
As an example, the radioactive decay of carbon-14 is exponential with a half-life of 5,730 years.
A quantity of carbon-14 will decay to half of its original amount (on average) after 5,730 years, regardless of how big or small the original quantity was.
After another 5,730 years, one-quarter of the original will remain.
The lab also uses Carbon-14 analysis for natural product source testing on materials such as flavors, fragrances, essential oils, cosmetics and supplements to identify petrochemicals.
) is the time required for a quantity to reduce to half its initial value.
The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo, or how long stable atoms survive, radioactive decay.
The term is also used more generally to characterize any type of exponential or non-exponential decay.
The lab also provides stable isotope analyses on a standalone basis.
